INTRODUCTION 



With the steadily increasing interest in mosquitoes and mosquito 

 control in the Southeastern States, the need has arisen for a separate 

 publication on the species of this region, bringing together informa- 

 tion widely scattered through the literature and providing a con- 

 venient means for their identification. Such an account has there- 

 fore been prepared, which includes the species recorded from the 

 nine States east of Texas and Oklahoma and south of the latitude of 

 the Virginia-North Carolina border. The information has been com- 

 piled from various published sources, with additions and certain cor- 

 rections from the writers' own studies, which have been conducted 

 principally in Louisiana and Florida. The purpose of the publica- 

 tion is to provide a reference work for collectors and others who work 

 with the mosquitoes of this region. It contains notes on the habits of 

 the species, their distribution, economic importance, and methods of 

 control, together with descriptive keys for the identification of adults 

 and larvae. Because fewer species are considered than in the more 

 general reference works, an effort has been made to simplify the 

 identification of adults by eliminating some of the more obscure 

 generic characters in favor of others that can be made out with less 

 difficulty. All the genera have therefore been included in a single
